Mapping Green Transformation Technologies to the Patent Literature
The GXTI consists of three levels of hierarchy as follows:
- Large classification (consisting of 5 perspectives and 4 transversal perspectives common to those perspectives)
- Medium classification (consisting of 32 technologies)
- Small classification (consisting of 86 technologies)
The Level 2 Category and the Level 3 Category are individual technologies in each Level 1 category. The Level 3 categories illustrate what specific technologies are involved in the Level 2 Category.
For each GX technology, the JPO provides a patent search formula. In order to understand the population, the patent search formula from the JPO was used for each category. Automatic classifications were created based on the patent search formula and on the relationships among the three classifications.
Such a detailed mapping of technology provides deep insights into the GX-related efforts toward the five major Green Transformation Technologies. The GXTI dashboard helps companies search for patents related to green technologies. By using the GXTI, a company can see how many patent applications they have in each technology category, and compare their strengths with other companies. This information can be useful in planning business and patent strategies.
